Test Connections to the Field Wiring Compartment
During calibration set up the transmitter as shown in figure 8. Except for 4211 and 4221 transmitters, the field circuit
printed wiring board is used. A 4211 or 4221 transmitter uses a barrier strip (key 11, figure 4) mounted in the field
wiring compartment for field wiring connections. For calibration and bench check of the 4211 or 4221 transmitter,
make connections to the barrier strip (key 11).
For a 4210, 4215, or 4220 transmitter with position switches, the transmitter can be calibrated with or without the
position switch outputs being connected.
Note
On units with position switches, the (R) terminal on TB3 must be connected to the power supply negative (-) terminal for proper
instrument operation, even if the position switch outputs are not used.
For a 4211 or 4221 transmitter without position switches, use a two wire system with the indicating device installed as
shown in figure 8.
